Option 3 : Johann Wolfgang Dobereiner

Johann Wolfgang Dobereiner made his first observation as a catalyst on Platinum and discovered similar triads of elements which led to the creation of the Periodic Table of Elements.

He was a German chemist best known for his work, which foreshadowed the periodic rule for chemical elements, and for inventing the Döbereiner's first lighter.
Döbereiner is also known for his discovery of the furfural, for his work on using platinum as a catalyst.
Dmitri Mendeleev produces a farsighted interpretation of the periodic element table.
Hans Christian Oersted discovered that electric currents produce magnetic fields, which was the first relation between magnetism and electricity.
Michael Faraday contributed to the study of electromagnetism and electrochemistry.

Option 3 : Johann Wolfgang Dobereiner

The correct answer is Johann Wolfgang Dobereiner.

Johann Wolfgang Dobereiner is a German chemist.
He is well-known for his discovery of furfural.
Dobereiner's triads
- He arranged certain elements with similar properties in a group of three.
- The atomic mass of the middle element was nearly the same as the average atomic mass of the first and third elements.
- These sets of elements were known as Dobereiner's triads.

Dmitri Mendeleev
- He was a Russian chemist and inventor.
- He is best known for formulating the modern-day periodic law and the periodic table of elements.
- He also predicted the properties of three elements that were to be discovered.
- He is referred to as the 'Father of the Periodic table'.
Hans Christian Oersted
- He was a Danish physicist and chemist.
- He discovered that electric currents are creating magnetic fields.
- He found the first connection between electricity and magnetism.
Michael Faraday
- He was an English scientist.
- He majorly contributed to the study of electromagnetism and electrochemistry.
- His discovered the principles of electromagnetic induction, diamagnetism and electrolysis.
